Switch SAI for Coral Reef

drop SAI and pay oop for FF, and add other signature restaurant

I am taking my mother in November, and meeting my cousin. Cousin hasn't been before. Mother and I have. Mother is 85 with dementia, so everything is kind of new even if it isn't. So far, I have scheduled:

Sci Fi for dessert after Fantasmic-- have done, but want to share atmosphere

San Angel Inn dinner, sharing with mom-- have done once, recent reviews and atmosphere make me want to do it again

Boma dinner--always love this

Restaurant Marrakesh CP package--never been

Flying Fish, share with mom, OOP with TIW?--never been

1900 Park Faire breakfast OOP with TIW--have done, but love strawberry soup, and want characters for my mom. Switched from dinner to BF so I could fit in Boma.

I have also thought about trying Turf Club(want to try lamb chops), or doing Coral Reef or Kona again. The only ressie I can see cancelling is SanAngel. Or if I pay OOP for 1900 PF and both meals at Flying Fish , I would still have 2TS credits left(share with mom and cousin has own).

I kind of want a balance of really good food and special experiences.
Should I keep SAI, or switch, or just add one of the others. Which one:
